Trademark Registration in Thailand
Plan trademark registration in Thailand: owner, clearance search, goods and services, application documents, fees, examination, opposition, international routes and renewal.

Trademark registration in Thailand: search, filing and renewal
Choose the right owner, search similar marks and define the goods and services before filing. Application, examination, publication and registration are separate stages. Use the amended Act for procedural periods, keep official evidence and plan renewal from the actual register dates.
Find what you need
Use a section below to plan your next step.
Decide what you need to protect
A trademark identifies the commercial source of goods or services. A company name, domain or social handle does not by itself create a registered Thai trademark. Identify the word mark, logo, Thai-language version and other signs that the business actually uses or plans to launch.
Choose the intended owner before filing. The operating company, founder, parent and distributor are different possible applicants with different consequences. Check the rights to commissioned artwork and any pre-existing brand. An agency filing in its own name can leave the business without the ownership it expected.
Search before spending on the launch
Use DIP’s current search to investigate identical and similar marks, relevant goods and services, owners and status. Consider spelling, sound, meaning, transliteration, Thai-language variants and logos rather than searching only the exact English name.
Treat a search as a risk assessment, not a guarantee. Database coverage, pending applications, similarity analysis and other rights can matter. Have a specialist review important conflicts before committing to packaging, signs, stock or advertising.
Keep the search date, terms, relevant results and the decision made. If you change the name or logo materially, review the new version rather than assuming the original search still answers the question.
Choose goods and services carefully
Describe the goods or services that need protection and identify their classes. A class number is a filing category, not unlimited protection for everything in an industry. A vague or unsuitable specification can create an examination problem or leave the important offer outside the registration.
Consider the actual business and realistic expansion, with advice on accepted wording and Thai-language requirements. Compare word and logo applications on what they protect. Changing a combined logo later can raise different questions from maintaining the same word brand.
Budget for each mark, relevant class and item structure. Do not ask a filing provider only for the cheapest package without checking who owns the result and exactly which goods and services it covers.
Prepare the applicant, mark and authority file
Confirm the current DIP checklist for applicant identity or incorporation, address for service, representation of the mark, goods and services, power of attorney and any priority claim. Overseas applicants should check local contact or agent arrangements and document certification.
Make the owner’s name and address consistent across the application and authority documents. Review translations and transliterations. Keep the final image and specification that will be submitted; an informal mock-up is not a substitute for the actual filed representation.
If an earlier foreign filing may support priority, obtain advice promptly on eligibility, timing and evidence. Do not assume that a foreign registration automatically protects the mark in Thailand or that a missed priority deadline can always be restored.
Separate application, registration and professional fees
DIP’s published ordinary schedule distinguishes an application fee from a later registration fee. For one item in one class, it lists 1,000 baht for application and 600 baht for registration. This narrow example is not a quote for every mark or multi-class portfolio.
Check the current schedule for the actual item and class structure, mark size, amendments, appeals, renewals and other steps. Ask the provider to separate official fees, searches, drafting, translations, representation, responses and tax. A low filing price may exclude the later registration or an objection response.
Pay through verified channels and retain official receipts. An invoice from a private register or unfamiliar overseas service is not necessarily an official DIP fee.
Understand filing, examination and publication
Filing establishes an application; it does not guarantee registration. DIP examines the mark and application and may require clarification, amendment or a response. Assign someone to monitor official correspondence and record the date of receipt of each notice.
The amended Act provides a 60-day publication opposition period. Older material referring to 90 days can be out of date. Objections, opposition, counterstatements and appeals have their own rules and time limits, so obtain case-specific advice immediately on receipt of a notice.
If registration is ordered, complete the required fee and remaining steps within the actual notice deadline. Confirm the final certificate and register entry. Do not report the mark as registered merely because an application receipt has arrived.
Choose domestic and international routes deliberately
Thailand protection and protection in another market are separate. International trademark systems can simplify a filing route for designated territories, but local examination, objections and conditions still matter. They do not create one automatic worldwide brand right.
Discuss the applicant’s eligibility, base application or registration, countries, goods and services, costs and risks before choosing a route. Keep domestic and international references linked in the IP register so deadlines and ownership remain consistent.
Maintain the owner, use records and renewal calendar
The amended Act provides a ten-year term using its statutory registration-date rules, with registration generally deemed from the application date. Check the official expiry record rather than starting a new ten-year clock from the day a certificate is delivered.
Section 54 provides renewal in the three months before expiry and a late route within six months after expiry with a 20% surcharge. Have the actual dates, conditions and current procedure confirmed by the responsible adviser. Treat the late route as a remedy to assess, not the normal planning deadline.
Keep the owner and correspondence address current and retain evidence of use. Review assignments, licences and any required recording when the business changes. Do not assume that a company sale, rebrand or distributor change automatically updates the trademark register.
If someone copies the mark or challenges the application
Preserve the filing and registration records, dated use evidence, relevant products or packaging, URLs and communications. Ask a Thai IP adviser to compare the alleged use with the actual right and assess the appropriate response, cost and remedy.
Avoid public accusations, threats or a platform complaint based only on a similar-looking name. Ownership, validity, goods, exceptions and evidence matter. If you receive a demand or official notice, record its receipt date and obtain advice before the response period runs out.
Before instructing a filing
Common questions
Does a DBD company name protect my trademark?
No. Company registration and trademark protection serve different purposes. Check the mark and goods or services through DIP.
Is a search result a guarantee?
No. Similarity, earlier rights, pending applications and the specification require assessment.
Is the opposition period still 90 days?
The amended Act provides 60 days from publication. Use the current law and actual notice for procedural deadlines.
Can renewal be done after expiry?
The amended Act provides a limited six-month late route with a 20% surcharge. Obtain advice on the actual record and current procedure rather than waiting for that period.
